Integrated indicators for assessment of best management practices in tilapia cage farming

One of the ways to increase sturgeon aquaculture is the cage cultivation of commercial fish on small rivers of the Krasnodar Territory. The projected cage farm is intended for the cultivation of sturgeon and tilapia in aquaculture. The production program assumes the annual production of up to 6.25 tons of commercial fish weighing 1.2—2 kg of sterlet and at least 160 kg of tilapia, with an individual weight of 250—280 g, from each involved cage. The paper describes the area of the cages, the composition of the cage farm and the technology of growing sturgeon (sterlet) and tilapia. Fish farming calculations (stocking, fish growth, feed, yield of commercial fish) are given. The possibility of placing a garden farm on the Kalaly River of the Novopokrovsky district of the Krasnodar Territory is justified and calculated.

Golden mussel is an invasive species in South America that causes environmental and economic damage due to the formation of large colonies without natural predators. This study aimed to test the agricultural use of golden mussel shell as a limestone substitute, as the shell is rich in calcium carbonate. The experiment was carried out in pots, with eight treatments (sandy soil; clay soil; sandy soil + 1.0 Mg ha−1 of limestone; clay soil + 1.0 Mg ha−1 of limestone; sandy soil + 1.0 Mg ha−1 of fresh shell; clay soil + 1.0 Mg ha−1 of fresh shell; sandy soil + 1.0 Mg ha−1 of calcined shell; clay soil + 1.0 Mg ha−1 of calcined shell), in addition to the application of the following fresh and calcined shell doses: 0, 1.0, 1.5 and 2.0 Mg ha−1. Rice was cultivated in all treatments, and the soil fertility and rice shoot and root dry masses were evaluated. The shell provided good chemical conditions to the soils and raised their pH and phosphorus and calcium contents. The agricultural use of golden mussel shell showed to be efficient for soil correction and can be considered an alternative to limestone.
